## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of engine power(total) - nonmechanical, go-around (vfr)
  - emergency procedure - simulated, pilot in command(cfi)
  - precautionary landing - simulated, dual student
  - weather condition - temperature extremes (contributing factor)
  - powerplant controls - improper use of, pilot in command(cfi) (cause)
  - go-around - initiated, pilot in command(cfi)
- Forced landing, landing - flare/touchdown
- Nose over, landing
  - terrain condition - snow covered (contributing factor)

## Analysis

THE STUDENT & INSTRUCTOR PLT (CFI) WERE ON AN INSTRUCTIONAL FLT ON A COLD WINTER DAY (TEMP -10 DEG F). THE CFI STATED THAT WHILE PRACTICING TURNS AT 3000 FT MSL, HE CLOSED THE THROTTLE TO GIVE THE STUDENT A FORCED LANDING EXCERCISE. HE STATED THAT CARBURETOR HEAT WAS APPLIED AFTER CLOSING THE THROTTLE, BUT MADE NO MENTION OF CLEARING THE ENG DURING THE DESCENT. AT APRX 150 TO 200 FT AGL, HE TOLD THE STUDENT TO EXECUTE A GO-AROUND. INSTEAD OF ADDING POWER, THE STUDENT EXTENDED THE FLAPS. AT THAT TIME, THE CFI TOOK THE CONTROLS & OPENED THE THROTTLE BUT THE ENG COUGHED ONCE, THEN STOPPED OPERATING. SUBSEQUENTLY, A FORCED LANDING WAS MADE IN APRX 3 FT OF SNOW & THE ACFT NOSED OVER. NO PREIMPACT, MECHANICAL PART FAILURES WERE REPORTED.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19830221004699A](https://openairdocs.org/incident/19830221004699A), Feb 21, 1983: Cessna 150G, Fairbanks, AK, Substantial damage. Engine would not run after glide for simulated emergency landing. Crash occurred during landing in deep snow.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
